Mozilla IT & Operations

We will have a scheduled downtime window this coming Thursday from 8pm to 11pm PDT. The following changes will take place:

* 8pm PDT – One of our primary database servers will be brought down to replace faulty hardware. This may effect addons, bonsai, firefoxday and other dynamic sites. Expected downtime is less than 15 minutes, but could run for the full window if issues are encountered.
* 8pm PDT – Adding firewall rules to internal networks. This will help improve network isolation and security. No expected downtime, but intermittent network connectivity is possible.
* 9pm PDT – irc.mozilla.org ssl certificate upgrade and software upgrade. 5 minutes or less of downtime is expected.
* 9pm PDT – NAS network settings changes. We will be updating network settings on our NAS. No expected downtime, but intermittent network filesystem access is possible for the remainder of the maintenance window.

Please let me know if you have any reason why we should not proceed with the planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window. Feel free to email infra@mozilla.org if you see issues past the planned downtime.
